If the scale factor of figure a to figure b is 7: 2 find the perimeter of figure a.

The perimeter is the sum of all sides of the given shape, so according to the scale factor, the perimeter of the Figure A is 122.50 units.

Given information:

The scale factor of fig. A to fig. B is 7:2

As, the proportion would be between the perimeters

So,

Now, we know that the perimeter is the sum of all sides of the given shape

Hence taking the values from the given figure and putting in the above expression

we get,

Hence, the perimeter of the Figure A is 122.50 units.

Step-by-step explanation:

The proportion would be between the permiters and the given ratio:

Where is the perimeter of the bigger figure and is the perimeter of the smaller figure.

Remember that the perimeter is the sum of all sides, using all given values and solving for , we have

Therefore, the permiter of Figure A is 122.5 units.
